Power Requirements
209
Wiring connections must be properly torqued. Many equipment manufacturers specify the proper connection
torque values for their hardware.
Ground connections must only be made on a conductive, nonpainted surface. When equipment vibration is
present, lockwashers must be used on all connections to prevent connection hardware from working loose.
Wiring for Power Conditioning Equipment
Power conditioning equipment sense wires must be routed well away from main power conductors and
electrical devices that might produce stray coupling between circuits. Stray coupling could interfere with
power conditioning sense circuits, thus nullifying their benefits.
Data Communications Cables
Route data communications cables away from areas of high energy electric fields created by power
transformers and heavy foot traffic. Use shielded data communications cables that meet approved industrial
standards to reduce the effects of external fields.
NOTE Hewlett-Packard supplies shielded data communications cables that comply with FCC
standards for Electromagnetic Interference (EMI). Approved cables reduce the risk of
high-speed data loss in serial data communications installations.
